About 1/3 of alligator nests are destroyed by predators (mainly raccoons) or flooding. The average clutch size of an alligator nest is 38. For nests that survive predators and flooding, an estimated 24 live hatchlings will emerge. Only 10 alligator hatchlings will live to one year. Of these yearlings, 8 will become subadults (reach 4 feet in length).

Fern leaves grow from a rhizome. Fern leaves are fan-shaped and also play an important role in reproduction. The production of spores occurs in structures called sporangia. These structures are found on the surface of the fronds, usually on the underside of the leaf. When the sporangia or spore casings dry out, the dispersal of spores occurs into the atmosphere. Certain fern species date back nearly 400 million years. There are about 12,000 fern species.
